Voltage to Current Module 0-5V to 4-20mA Current Transmitter Signal

The Voltage to Current Module is designed to convert a 0–5V voltage signal into a 4–20mA current signal, enabling long-distance and stable signal transmission in industrial automation systems. Voltage signals tend to weaken over extended transmission distances, but by converting them into current signals, this module ensures accurate and interference-resistant communication.

Operating on a 7–30VDC power supply, the module provides flexible compatibility with various system requirements. Both zero-point and full-scale (span) adjustments can be fine-tuned using onboard potentiometers for precise calibration. With isolation properties (non-optocoupler), it enhances reliability in control circuits.

Compact, lightweight, and reliable, this current transmitter is widely used in PLC systems, industrial controllers, sensors, and monitoring equipment where robust signal transmission is critical.
